Generally, it is a container made of stainless steel with a vacuum layer to hold water. It has a lid on the top and is tightly sealed. The vacuum insulation layer can slow down the heat dissipation of water and other liquids inside, achieving the purpose of insulation. The thermos cup evolved from the thermos bottle, and the insulation principle is the same as the thermos bottle, except that people make the bottle into a cup for convenience. There are three ways in which heat spreads: radiation, convection, and transmission. The silver cup liner inside the thermos can reflect the radiation of hot water, and the vacuum between the cup liner and body can block the transfer of heat, while the bottle that is not easy to transfer heat can prevent heat convection.

1. Before use, clean the inside and outside of the cup (lid) with neutral detergent in warm water.

To achieve the desired heat and cold retention effect of the cup (pot), it is recommended to first add hot water or ice water for preheating or pre cooling. Adding ice cubes during cooling will have a better effect.

To prevent leakage, please tighten the switch and cup lid clockwise when tilting the cup body.

2. Use to avoid dropping, collision or impact, which may cause deformation of the cup body and affect the effectiveness of the product.

Insulated switches, cup lids, and other accessories are made of food grade plastic according to national standards. Do not lose switches, cup lids, washers, and other accessories during use to avoid affecting normal use.

Avoid any form of direct heating or placement at high temperatures, as it may cause resin deformation, discoloration, and affect the effectiveness of product use.

Do not add dry ice, carbonated beverages, or other liquids that can generate high pressure to the vacuum cup. Do not add liquids containing salt such as soy sauce or soup to prevent corrosion of the cup body.

When cleaning, please use neutral detergent and warm water to clean. Do not use alkaline bleach, chemical cloths, or other cleaning agents.

After filling with perishable beverages such as milk, please drink them as soon as possible and clean them to avoid spoilage and rotting of the inner container.

Do not use for purposes other than heat and cold insulation.

When not in use for a long time, the inner container should be kept completely dry.

To prevent odors or stains, clean thoroughly after use and let it dry thoroughly.

Due to the presence of rust like red spots after using impure water, it can be thoroughly cleaned by soaking in diluted vinegar in warm water for thirty minutes.

Cup lid: Do not disinfect at high temperatures to avoid deformation. After cleaning, it should be confirmed that the sealing ring is installed properly
